General PrecautionsEBS00BKI
WARNING:
When replacing fuel line parts, be sure to observe the following.
●Put a “CAUTION: INFLAMMABLE” sign in workshop.
●Be sure to work in a well-ventilated area and furnish workshop with a CO2 fire extinguisher.
●Do not smoke while servicing fuel system. Keep open flames and spark away from work area.
CAUTION:
●Before removing fuel line parts, carry out the following procedures:
–a) Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container
in safe area.
–b) Disconnect battery ground cable.
●Always replace O-ring and clamps with new ones.
●Do not kink or twist tubes when they are being installed.
●Do not tighten hose clamps excessively to avoid damaging hoses.
●After installing tubes, make sure there is no fuel leakage at connections in the following steps.
–a) Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then
check for fuel leaks at connections.
–b) Start the engine and rev it up and check for fuel leaks at connections.

Air Bleeding
EBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel path as follows:
1. Move priming pump up and down to bleed air from fuel path.
2. When air is bled, pumping of priming pump becomes heavy stop
operation at that time.
3. Crank the engine until it starts. Do not crank the engine for more
than 30 seconds.
4. If the engine does not starts, stop cranking and repeat step 1
above.
5. If the engine does not operate smoothly after it has started, race
it two or three times.
6. If air cannot be bled easily (pumping of priming pump does not become heavy), disconnect feed-side of
hose between fuel filter and electronically controlled fuel injection pump. After that, operate priming pump
and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine
mount insulator.
Draining Water from Fuel FilterEBS00MRU
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:
●Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.
●Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mount insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-16, "
Air Bleeding" .
5. Start engine and check for fuel leakage.

WARNING:
Be sure to read “General Precautions” When working on fuel system. Refer to FL-14, "
General Precau-
tions" .
1. Disconnect battery ground cable.
2. Open fuel filler lid.
3. Open the filler cap and release the pressure inside the fuel tank.
4. Check fuel level on level place. If gauge indicates more than the
level shown in figure (full or almost full), drain fuel from fuel tank
until gauge indicates level shown in figure or below.
In case of fuel pump does not operate, take following procedure.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel
filler tube through fuel filler opening to draw fuel from fuel filler
tube.
b. Disconnect fuel filler hose from fuel filler tube.
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel
from fuel tank.
●As a guide, fuel level becomes the position shown in figure or
below when approximately 15 liter (13-1/4 lmp qt) of fuel are drained from full tank.
NOTE:
Adjusting fuel level is to prevent fuel from spilling, when fuel level sensor unit is removed.
